30 This is a convenience function for extracting a captured substring. The
31 arguments are:
32 <pre>
33 <i>subject</i> Subject that has been successfully matched
34 <i>ovector</i> Offset vector that <b>pcre_exec()</b> used
35 <i>stringcount</i> Value returned by <b>pcre_exec()</b>
36 <i>stringnumber</i> Number of the required substring
37 <i>stringptr</i> Where to put the string pointer
38 </pre>
39 The memory in which the substring is placed is obtained by calling
40 <b>pcre_malloc()</b>. The convenience function <b>pcre_free_substring()</b> can
41 be used to free it when it is no longer needed. The yield of the function is
42 the length of the substring, PCRE_ERROR_NOMEMORY if sufficient memory could not
43 be obtained, or PCRE_ERROR_NOSUBSTRING if the string number is invalid.
